Errors all over Google SERPS- This site may harm your computer

Update: Approximately 30 minutes ago (It’s now 15:20 on Saturday 31 Jan), results pages at Google began reporting Malware errors on all of their results. Here’s my post / screenshots on the issue so far.

Much to my alarm, the SERPS are displaying the “This site may harm your computer” link for my website, and most of the others above and below on page 1:

Thing is, there’s no problem with my site, nor any of the others in the list. Different queries are producing the same result:

When Google doesn’t trust your site in the results it links via this page.The “this site may harm your computer” link is currently producing a temporary server error page.

Is there something broken at Google today? Twitters are coming in thick and fast confirming the issue is impacting most if not all of Google’s SERPS meaning no traffic is being sent directly to any of the websites displayed in the results. That’s a serious problem for traffic levels across the world.

More to follow.

Update: The problem appears to be resolving – where the error only appears on every 4th refresh of the SERPS.

“We periodically receive updates to that list and received one such update to release on the site this morning. Unfortunately (and here’s the human error), the URL of ‘/’ was mistakenly checked in as a value to the file and ‘/’ expands to all URLs.”
